I have 2-10 month old barred rock ladies. They had been laying fine, not every day, but at least 4-5 days a week. About 3 weeks ago they completely stopped. We haven't changed anything. We live in Ohio, so obviously have had snow and then some 50 degree days off and on. I've seen a few feathers laying around, but not others we've had when molting. My husband is getting frustrated because of the cost of organic feed for chickens not laying. Is there anything I can do to help?
